WHEELED CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 614,727, dated November22, 1898.

' Application filed October 2,1896. Serial No. 607,686. (No model.)

To all whom it may concern.-

Be itknown that 1, CHARLES L. KING, acitizen of the United States,residing at Stella, in the county of Richardson and State of Nebraska,have invented certain new and useful Improvements in -WheeledCultivators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention has reference to a novel construction in a wheeledcultivator; and it consists in the features of construction andcombinations of parts hereinafter fully described and specificallyclaimed.

In the accompanying drawings, illustrating this invention, Figure 1 is aperspective view. Fig. 2 is a top plan. Fig. 3 is a verticallongitudinal section. Fig. at is an enlarged perspective view of thecultivator, and Fig. 5 is a detail view illustrating the couplingbetween the beams.

Referring now to said drawings, 1 indicates the pole or tongue of thecultivator, which is connected at its rear end with the archframe 2. Infront of the arch-frame 2 and connected with said tongue 1 is the frame3 for the cultivator-beams. This frame 3 is made in one piece, itscentral portion being secured to the tongue, while it is bent downwardlyon both sides thereof and then bent outwardly to form horizontal bearingportions v t and then bent upwardly and rearwardly and connected withthe side bars 5 of the frame. The forward ends of these side bars arealso connected with the central portion of the frame 3.

The wheels 6 of the cultivator are fastened upon axles 7, that areconnected with the lowerbent end 8 of a spindle 9, that is mounted inbearings on the depending part of the archframe 2. The upper end of thespindle 9 is provided with a forwardly-projecting arm 10. These arms 10on both sides of the machine are connected together by a bar 11, pivotedto each of the arms 10. This bar 11 is connected by means of a brace 12with a lever 13, pivoted on the rear end of the tongue 1, having a lug1i at its forward end adapted to engage a rack 15. The bar 11 acts as aspring to draw the lug 14 into the teeth of the rack 15, so that when itis desired to shift the bar rear ends.

11 the rear end of the lever 13 must be pressed downwardly to releasethe lug from the rack. It will be noticed from the above that when thewheels are turned to guide the cultivator the entire frame of themachine moves to one side a few inches and even before the wheels moveforward, while at the same time the pole 1 and connected at their upperendswith the arms 19 of a lever 20, carrying a suitable detent to engagea rack 21 on the tongue to hold the lever in any adjustable position. Itwill be seen that by turning the lever on its pivot'the doubletree israised or depressed, so as to adjust the-draft according to the work tobe accomplished. Forinstance, when the cultivator is used as awalking-cultivator the doubletree is turned to the lower limit of itsmovement.

The seat for the driver is preferably supported by the ends of the sidebars 5, as shown in the drawings. The side bars are provided with lugs22, which engage a spring 23, carrying the seat 24.

The cultivator-beams25 are two in number and are pivoted at their frontends to the bearing portion 4 of the frame 3. These cultivator-beamscarry the shovels 26 at their The cultivator-beams are suitably bracedtogether by braces 27, which are connected rigidly with the outside beamand adjustable with the inner or short beam. The outer beams 25 are eachprovided with a handle 28, by means of which the cultivator can be usedas a walking-cultivator. 0onnected with each of the outside beams 25 isan upright rod 29, connected at its upper end with a lever 30, pivotedto the side bar 5 of the machine, by means of which the beams can beraised or lowered, said lever 30 being held in any adjusted position bya circular rack 31, and it will be seen in this manner the beams can beraised or lowered, as desired. The cultivator-beam is pivotallyconnected at its forward ends with a coupling 32 and can be allowed toact loosely or can be made rigid with relation to the coupling by theinsertion of a loopbolt in the rear end of the forward coupling 32, asbest shown in Fig. 5.

It will be seen that the construction for supporting and guiding thewheels is compact, easily operated, responds quickly to theoperating-lever, and includes a construction of connecting-bar whichoperates as a spring for actuating the detent devices by which theguiding mechanism is held in any desired adjustment.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a cultivator, the combination with a frame, having an arch 2, ofupright and rearwardly-inclined spindles mounted in bearings upon theend portions of said arch, outwardlyextending axles at the lower ends ofsaid spindles, and carrying wheels, forwardly-extending arms upon theupper ends of said spindles, a spring-bar connected with said arms, anda lever connected with said springbar and having a lug adapted to engagea toothed rack 15.

2. In a cultivator, the tongue, side bars, wheels and shovel-beams, incombination with a frame 3, having a forward horizontal portionconnected with said tongue, and side bars, depending portions at theouter ends of said horizontal portion having bearing portions 4 at theirlower ends upon which the shovel-beams are supported, and upwardly andrearwardly extending end portions connected at their upper ends withsaid side bars, substantially as described.

In a cultivator the combination with a frame from which thecultivator-beams are supported, of the cultivator-beam 25, acoupling-plate on said beam and embracing the frame, a pivot-pin forsaid beam, and an adjusting-pin upon said plate to engage said beam,substantially as described.

4. A cultivator substantially as described comprising the wheels, theirguiding-supports comprising upright shaft portions suitably journaledand provided with the upper crankarms and with the lower crank-arms andwith the spindles on the latter, the bar connected directly with theupper crank-arms whereby it connects the opposite Wheel-supports and maypositively move the same and means for adjusting the said parts toeffect a guiding movement of the wheels and the arch to which theupright shaft portions are journaled substantially as shown anddescribed.

5. The improvement in cultivators substantially as herein describedcomprising the framing, the arch having upright side portions providedwith bearings, the wheels, the wheel-guiding supports comprising upperand lower cranlcarms and the intermediate upright portions journaledbetween the end cranks to the bearings of the uprights of the arch, thewheel-spindles on the lower crankarms, the spring-bar connecting theupper crank-arms, the lever, the rack for engagement by said lever andthe connection between the lever and the spring-plate, the latteractuating the lever normally into engagement with the rack allsubstantially as shown and described.

6. The improvement in cultivators comprising a supporting-frame,wheel-guiding supports having journaled upright portions inclined to thevertical substantially as described, crank-arms at the lower ends ofsaid upright portions and extending normally in the direction of motionof the implement, lateral spindles on said crank portions and wheels onsaid spindles, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES L. KING.
